Suggest Treatment For Vaginal Bleeding After Colonoscopy

I had a colonoscopy on Tuesday, haven t had a bm yet, am feeling full/bloated, and this afternoon started bleeding from vagina, not rectum. I m 53. It was my first colonoscopy. No polyps. I am in excellent health. Am vegetarian, do yoga & bike daily. Still have my periods on a 4 week cycle and have never spotted before. The blood was dark reddish-brownish, and mucous-like, about 3 tbs, and it s happened 2 more times since this afternoon.
